Method and apparatus for performing semi persistent scheduling reactivation between sidelink and uplink in wireless communication system
While a user equipment (UE) performs a periodic transmission on a first link or a first carrier by using a semi-persistent scheduling (SPS) resource for the first link or the first carrier to an eNodeB (eNB), the UE may receive a SPS resource for a second link or a second carrier from the eNB. Or, a certain event may occur. Then, the UE stops using the SPS resource for the first link or the first carrier, and performs a periodic transmission on the second link or the second carrier by using the SPS resource for the second link or the second carrier to the eNB.
1. A method for a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station (BS), a first semi-persistent scheduling (SPS) configuration related to a SPS resource for both a sidelink (SL) and an uplink (UL);
configuring the SPS resource based on the SPS configuration;
receiving, from the BS, a SL SPS activation command for a periodic transmission on the SL;
performing the periodic transmission on the SL using the SPS resource upon receiving the SL SPS activation command;
receiving, from the BS, a UL SPS activation command for a periodic transmission on the UL;
stopping the periodic transmission on the SL using the SPS resource upon receiving the UL SPS activation command; and
performing the periodic transmission on the UL using the SPS resource
upon receiving the UL SPS activation command.
2. A method for a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station (BS), a semi-persistent scheduling (SPS) configuration related to a SPS resource for both an uplink (UL) and a sidelink (SL);
configuring the SPS resource based on the SPS configuration;
performing a periodic transmission on the UL using the SPS resource to the BS;
detecting that a certain event occurs,
wherein the certain event includes at least one of handover, handover failure, radio link failure (RLF), connection establishment, or connection reestablishment;
stopping the periodic transmission on the UL using the SPS resource upon a detection that the certain event occurs;
performing a periodic transmission on the SL using the SPS resource to the BS upon the detection that the certain event occurs;
detecting that the certain event ends;
stopping the periodic transmission on the SL using the SPS resource upon a detection that the certain event ends; and
performing the periodic transmission on the UL using the SPS resource to the BS
upon the detection that the certain event ends.
